inflection x^3-2x^2-4x+4

Solution

inflection points

x^{3} - 2 x^{2} - 4 x + 4

Solution

(\frac{2}{3}, \frac{20}{27})

Solution steps

f^{''} (x) = 6 x - 4

Find intervals:

Concave Downward

: - \infty < x < \frac{2}{3},

Concave Upward

: \frac{2}{3} < x < \infty

Plug

x = \frac{2}{3}

into

x^{3} - 2 x^{2} - 4 x + 4 : \frac{20}{27}

(\frac{2}{3}, \frac{20}{27})

Popular Examples

f (x) = (x + 3)^{\frac{2}{3}}

inflection f(x)=x^2e^{7x}inflection points

f (x) = x^{2} e^{7 x}

parity sqrt(4x^2e^{x^4)+1}parity

4 x^{2} e^{x^{4}} + 1

critical f(x)=x^3-3x^2-9x+4 critical points

f (x) = x^{3} - 3 x^{2} - 9 x + 4

asymptotes of f(x)=-2+1/x asymptotes

f (x) = - 2 + \frac{1}{x}
